Conditions

Sexually Transmitted Diseases

Keywords

Synthetic Male Condom; Slippage-Breakage Study

Outcome Measures

Primary Outcomes (3)

• Clinical breakage

  Clinical breakage is defined as breakage or tearing during sexual intercourse or during withdrawal of the male condom from the vagina. Clinical breakage is breakage with potential adverse clinical consequences. The clinical breakage rate is calculated by dividing the number of male condoms reported to have broken or torn during sexual intercourse or during withdrawal by the number of male condoms used during vaginal intercourse.

  3 - 5 months

• Clinical slippage

  Clinical slippage is defined as a condom slipping completely off the penis during sexual intercourse or during withdrawal from the vagina. The clinical slippage rate is calculated by dividing the number of male condoms that slipped by the number of male condoms used during vaginal intercourse.

  3 - 5 months

• Clinical failure

  Clinical failure is defined as a clinical breakage or a clinical slippage. The clinical failure rate is calculated by dividing the number of male condoms with a clinical failure by the number of male condoms used during vaginal intercourse.

  3 - 5 months

Secondary Outcomes (4)

• Genital discomfort

  3 - 5 months

• Acceptability i.e Comfort in use, ease of fitting and removal, like or dislike of product attributes, adequacy and feel of lubrication.

  3 - 5 months

• Non-Clinical breakage

  3 - 5 months

• Non-Clinical slippage

  3 - 5 months
